On Oct 16th, the International Day for the Protection of the Ozone Layer, the Ministry of Ecology and Environment of China announced that China has reduced ozone-depleting substances by 628,000 tons since joining the Montreal Protocol on Substances that Deplete the Ozone Layer in 1991, accounting for more than half of the reductions made by developing countries.
The reduction has prevented greenhouse gas emissions by more than 26 billion tons of carbon dioxide (CO2), playing an active role in the gradual recovery of the world’s ozone layer and mitigating climate change.
The protocol, signed in 1987, aims to gradually phase out the production and use of ozone-depleting substances through global action. The parties to the protocol adopted the Kigali Amendment in 2016 to control, control and reduce hydrofluorocarbons (HFCs), a potent greenhouse gas that causes global warming. Scientific assessments suggest that if the international community implements the Kigali Amendment’s requirements for control and control, it can limit the rise in global average temperature by up to 0.5 degrees Celsius by 2100.
According to documents from the Ministry of Ecology and Environment, China has taken several measures to promote the implementation of HFCs control and control:
- it has established and strictly implemented an HFCs import and export permit management system,
- strengthened scientific and technological research into the implementation of HFCs control and control,
- in addition, industries such as automobiles and home appliances were accelerating research and development of substitutes and alternative technologies for HFCs, promoting industrial transformation and upgrading through the implementation of the treaty.
